Aston Martin V8 Vantage

Awesome sauce! So excited for this one Blake!!

[Exidous]

It seemed like you had more that you had to figure out for control and a piggyback could act as a CAN message gateway between the GM and Aston stuff. I was thinking much smaller that a V8 ECU. More like a MaxxECU Sport or Mini. It could also act as the data logger.

Fair.   With a Holley I'd still have to do the CAN gateway, the Maxx -might- let me output enough custom CAN to run my gauges/stock stuff, but I think I'd still have to put in the gateway with that, too, and then I'd need to tie into a bunch of OEM sensors (or add additional ones).

I'd still have to control the fuel pump with the GM ECU as well, since it needs to PWM it to maintain fuel pressure.   I guess I could build a custom PWM setup via the Maxx, etc. but I don't think that's less work than running the GM bits.

If Maxx could easily do standalone of direct injection, I'd totally have done that, though.

Totally fair on the DI support. I've been bugging Nathanael about it on and off for two years now.

The MAXX only has 10 discrete can outputs but each can have data masks. It has test outputs that can run indefinitely for things like check bits to to enable operation. If more were needed I'm sure Natanael could add them fairly quickly.

Exidous:

I have a MaxxECU Sport I'll be using on my racer. 
I think I have enough analog and digital I/O, but I might could use a few more.
Is there an inexpensive CAN I/O module available, that would give me another 4 or so inputs and outputs?

Thanks,
David

Cheapest is the canchecked MCE/CFE18. It adds about 7 DINs, 9 AINs and 3 low current outputs. Enough for a 1w bulb or so. Or a small relay. About $125 for just the board. Maxx has a default tune with all the can data prepopulated.

Just that one board has all of my tactile inputs at the dash going into it. Lights, switches, pedals. It drives my CEL, HB and ABS lights.

Vadpro is their US distributor.

HB light?   Hot boi light?

That should work nicely.

This thing is going to be so wicked!

[Exidous]

HB light?   Hot boi light?

High beam hot boi

[digitalsolo]

High beams.  Lame.  Hot boi button is better. 

I think it should turn on an RGB underbody kit that flashes while playing EDM rave music.

Well, mild setback.  I tried to fire up the ECU and read it with HP Tuners.  No dice.   I'm fairly confident the ECU is bad from the crash the donor was in, as there is physical damage to the case (connectors are cracked and fins are broken).  On further inspection it has a couple rattles inside of it, which generally isn't good, LOL.

When hooked up, it blows the main ECU feed fuse every time.  I've double checked that power is going where it's supposed to, and it doesn't pop when the ECU isn't plugged in.

Ordered a replacement ECU up, that'll be here next week.  So this weekend I'll keep working to finish the rest of the chassis wiring work.  The good news is that the when testing the controls for the chassis side wiring that runs the ECU, all of that seems to be working as intended.

Sounds like a sign to put a Motec on it...

[digitalsolo]

Shoot, I'm already like 35k into this swap, I don't particularly want to drop 12k on a Motec.  I mean, I kinda do, but I'm not gonna.   I'd rather spend that on coilovers and carbon fixed bucket seats, which are probably my next add-ons (next year), along with probably redoing the engine harness with mil-spec wiring/raychem shrink and ripping the front chassis power harness out and de-pinning the extra bits I don't need any longer.

Funny story, I needed a VIN for getting my ECU reprogrammed, but I don't have a VIN on the engine and can't talk to the ECU that had the VIN in it.   So what to do?

Well get on eBay and find the right year/option Z06 and just use that VIN.  So my ECU VIN when I run the car will say it's some random Z06 off eBay.

edit: Now I'm looking at Motec solutions.  I hate you all.

EMTRON with a pair of Toyota DI drivers!!!!!

KV8 to be precise. The drivers can be had for about $100 each on eBay.

[digitalsolo]

I don't think there is any base tune available for the pump/injector profiling with Emtron on this platform.   That means manually profiling those which is, from my reading, a 20+ hour effort and really should be done with an engine dyno.    Same reason I didn't consider the Link G5 Voodoo.

It seems like Holley and Motec are the only ones with available profiles out of the box.

[Exidous]

That's a shame. Have you talked with EMTRON yet? My communications with them were always very helpful. Maybe they have something in the works.
